'Sand of the Sea' in the Bible

But Isaiah cries concerning Israel: Though the number of the sons of Israel be as the sand of the sea, a remnant shall be saved:

{ And I stood on the sand of the sea, and saw a beast coming up out of the sea, and he had seven heads and ten horns, and on his horns ten diadems, and on his heads names impiously irreverent.}

and shall go out to deceive the nations that are in the four corners of the earth, Gog and Magog, to bring them together to battle: the number of these is as the sand of the sea.
